FREIGHT-CA3 noor.

Application filed September 17, 1921. Serial No. 501,505.

The invention relates to metal car roofs and more particularly to the interlocking of metal roof sheets with a ridge cover, purlines and the eaves, so that the roof may be quickly and inexpensively applied; thatit may be flexible and easily replaced when repairs are necessary.

In order to make the invention more clearly understood there are shown in the accompanying drawings, means for carrying the same into practical effect, without limiting the improvements, in their useful applications, to the particular constructions which, for the purpose of example, have been delineated.

In the drawings, Figure 1 is an outside end View of a box car. Fig 2 is a fragmentary vertical section taken at the ridge and showing a construe-tion in which the combined ridge pole and cover is interlocked with the roof sheet by means of extended curls at the adjacent edges of both members. Fig. 3 is a fragmentary vertical section taken at the eaves and showing a similar interlockbetween the roof sheet and the eaves strip. Figure 4 is a part section through the ridge pole and roofing plates showing the rigid connection ofthe pole with the carlines. Figure 5 is a part section through the purlin and roofing plates showing the tongue on the purlin and how it holds down the roof plates in their proper normal position, and ridge cover; 2, sheets; 5, the carlines eaves strips.

One side of the roof, A, is shown with the roof sheet extending from the ridge cover to the eaves; the other side, B, shows a purline interposed, of which, of course, there may be more than one.

The combination ridge pole and cover is formed of a section of metal strong enough to perform the duties of a ridge pole but it has its sides extended, as at C to perform all the functions of a. ridge cover, fully protecting the upper edges of the roof sheets from the weather. This element may therefore be properly described as a combination ridge pole and cover.

The eaves strips 7, are formed with a tongue projecting outwards as shown at D.

3 and i, the metal roof 6, the purlines; 7, the

1 indicates a combination ridge pole The purlines are also formed with a tongue as shown at E.

The metal roof sheets are formed substantially of an exaggerated S-shaped section, the upper hook or curve turned up underneath the ridge cover part'o-f the combination ridge pole and cover, the lower hook or curve of the S bent down and around the tongue 1 formed on the eaves strip, or on the purlme at E. They slide endwise into place.

\Vhere the sheets interlock with the tongue on the purlines, they also interlock with each other. The edges of the sheets may be further interlocked with the various elements composing the roof as a whole but in various other forms as may be found most practicable; a design for one method being shown in Figures 2 and 3. WVe therefore claim. in

our invention that not only should the edges be turned up or down and inwards or outwards as shown in Figure l, but that thev may be further corrugated as may be necessary.

WVhat we claim is:

1. In a flexible metal plate-car-roof, the

combination of a skeleton roof frame including side plates and purlins, with carlines having their apices elevated above the roofing surface at the ridge and rigidly attached to an, outside combined ridge pole and ridge cover which has its edges interlocked to form weather' noof with the upper edges of longitudinally disposed load supporting roofing plates whieh rest directly upon the car-lines and purlxns.

2. In a flexible metal plate-car-roof, the

combination of a skeleton roof frame including side plates and purlins, with a combination ridge pole and ridge cover located above the upper surface of the roof, rigidly at tached to the carlines and having its edges loosely interlocked to provide weatherproof with the upper edges of load supporting roof plates longitudinally disposed.

3. In aflexible metal plate-car-roof, the combination of a skelton roof frame including side and end plates, carlines and purlins, of longitudinally disposed roofing plates, means for weatherproofing. them at the ridge and eaves and having portions of said plates tucked in underneath portions of the purlins to prevent Vertical displacement of said plates with reference to the purlins but allow relative flexibility thereto in a horizontal direction.

4. In a flexible plate-car-roof, the eombination in a skeleton frame of purlins having tongue like projections on their upper edges, said tongues being substantially parallel to the surface of the roof and adapted to inter lock with and hold down longitudinally disposed roofing plates.

5- In a flexible plate-canreof, longitudinally disposed roofing plates weatherproofed at the ridge and caves and interlocked together weatherproof at the purlins and enclosing within the interlocking a protruding tongue attached to the purlin to restrict the Vertical displacement of the plates relative to the roof frame.

6. In an all metal plate-car-roof a combination ridge pole and ridge cover interlocked weatherproof with the roofing plates longitudinally disposed and adapted to and. acting as the sole support of the running board brackets and running board for the entire length of the ridge and to thus avoid structnral and mechanical interference between the running board and the roofing plates; with means for attaching the brackets.

7. An all metal car roof, comprising earlines, purlins, a combined ridge pole and cover member located at the ridge and pro vided with downwardly and inwardly turned lockin flanges and longitudinal load sustaining roof sheets directly supported upon the carlines and purlins, the ridge ends of said roof sheets being provided with flanges freely interlocl-tod with the ridge pole flanges and the eaves portions of said sheets being extended beyond the side wall of the car and provided with flanges that are freely interlocked with eaves strips.
